The temperature of surface seawater is Related to latitude and insolation (sunlight) Isotherms (lines of equal temperature) generally trend east-west * . Changes seasonally. *That is, the further north you go, the colder it gets. *That is, the further north you go, the colder it gets.

A thermocline is a Zone of rapid change in temperature that separates warm, low- density water from cold, high-density water. The permanent thermocline is A seasonal thermocline is also present at temperate latitudes.

At low latitudes, the thermocline is strong. At high latitudes (polar regions), no thermocline is present The water is cold from top to bottom.
